WINDING iymcmzNn.

Application filed October so, 1922. s m No. 597,979.

To all whom it may concern: I Be it known that I, CARL A. BRINK, a citizen of the United States, residing at Cranston, in the county ofProvidence, State of Rhode Island, have invented certain new and usefulImprovements in Winding Machines, of which the following is aspecification.

This invention relates to winding machines and consists of improvementsin the means for controlling the operation of the same.

The principal object of the improvement is to provide a more convenientmethod of starting and stopping the winding operation whereby theoperator is relieved fromfreac'hing for the controls and saved fromother motions so that the piecing up of ends may ;be accomplished withless effort and more expeditiously-to increase the rate of produc-'through manipulation of the foot-control so that the winding operationmay be started more promptly after the piecing up of the yarns.

Further objects of the lmprovement are set forth in the followingspecification which describes a preferred embodiment of the invention asillustrated in the accompanying drawings. In the drawings:

The present improvements are herein described and illustrated asapplied'to use in connection with a frictionor drum-driven type ofwinding machine in which the cop is rotated from surface contact withthe pelimited in-this respect as it may be adapted for othertypes'ofwinders having a positive drive for the package. 1

riphery of a drum or drive-roll; but it is to be understood that theinvention is not Referring to Fig. 1 of the present draw- Y ings thewindingmachine comprises, in general, a table or bed 2 supported from"suitable legs or standards 3 and mounting 'a double row of winding-headsor units 1-1 There may be any convenient number of winding-heads Hspaced at intervals along the bed 2, but in Fig, 1, only, two of theopposite units, are illustrated. Each unit .which are embodied inbox-like frames 4.

comprises, essentially, a constantly driven friction-drum or drive-roll5, a pivoted frame 6 for rotatably supporting thespindle or mandrel Ton. which the cop is wound, to adapt the latter to be held with itssurface in contact with the periphery "offthe drive-roll 5; a helicalcam 9, also continuously, driven; and a thread-guide 10 connected to bereciprocated from the camlongitudinally of the winding-mandrel todeposit the yarn .in cross-wound coils thereon.

The'above-named elements are common to practically all types ofdrum-winders 'and the drlvlng-connections foroperatlng thewmding-mechanlsm are not hereln shown or from overhanging arms 20 on theframe 4, an

of the. tube.

shown in Figs. 1 and 2. The outer ends of the arms 14 and 15 carry meansfor rotatably supporting the cop-tube or mandrel T on which the yarn orthread is wound, the tube consisting usually of a cylindrical billet ofwood provided with an axial bore t; For this purpose-the arm '14 isprovided with a bearing 21 in which is journaled a livespindle 22 havinga reduced end 23 adapted to enter the end of the bore t in'the tube T.The spindle 22 carries a disk 24 pro vided with spurs 25 which engage acrossslot .9 on the end of the tube T to key the latter rotatively withthe spindle. At the outer end of the opposite arm 15 is a similarlive-spindle 26 journaled in a bearing at the extremity of a lever 27.The lever 27 is pivoted at 28 to the side of the arm 15 'so that it maybe swung laterally in relation thereto to release the spindle 26 fromthe tube T, a spring 29 tending to normally maintain the spindle inplace in the bore 2 Referring to Figs- 1 and 2, the frame 6 supports themandrel or cop-tube T in position above the drive-roll 5 with theperiphcry of the tube in contact with the surface of the roll so that itwill be rotated therefrom to wind on the yarn. As the yarn is built upon the tube T and the cop increases in diameter the frame 6 will swingupwardly on its pivot 19. The movement of the tube T away from thedrive-roll 5is controlled by suitable dogging-means which acts toprevent the return of the tube toward the roll after it has recededtherefrom during the normal growth in the winding. The dogging-means isconstructed and arranged as later described.

Pivoted on a stud 30 which projects from the side of the arm 14 of theframe 6'is a lever 31 having a curved arm 32 arched above the bearing21. At the extremity of the arm 32 is a finger-piece 33 arrangedopposite a finger-rest 34 projecting from the end of the arm 14. Aspring 35 has its end hooked through a hole in the arm 32 of the lever-31 and is anchored at the opposite end to a lug 36 rising from the topof the arm 14. The spring 35 tends to rock the lever 31in the directionindicated by the arrow 6, Fig.

2. and the finger-piece 33 and rest 34 may be explained. During thenormal operation of v the machine the lever 31 is maintained in theposition illustrated in Fig. 2 by means of a detent-rod 37 which holdsit against the force of the spring 35. The rod 37 slides in a bearing 38on the side of the arm 14 and is beveled off or pointedat its forwardend to adapt it to engage a substantially V- shaped notch 39 at the endof a short arm 40 on the lever 31. Below the notch 39 the arm 40terminates in a wedge-shaped toe 47, while above the notch the end ofthe arm is of arcuate shape to provide an eccentric cam-face 51 whichserves a purpose as later explained. I

The opposite, inner end of the detent-rod 37 is bent at right-angles andhooked through a hole 41 in a sickle-shaped lever 42. The lever 42 ispivoted on a stud 43 held in a lug 44 rising from the rearwardcrossstrut 16 of the frame 6, and is controlled by a spring 45 anchoredto the end of a curved lever 46 to be later described. The spring 45tends to rock the lever 42 to urge the rod 37 into engagement with thenotch 39 in the arm 40 of the lever 31. The sickle lever 42 depend-sfrom its pivot-pin 43'a-t the front of the rod 19 on which the frame 6is hinged and reaches back in under'said rod in the curved portion 48which terminates in a downwardly-extending straight arm 49. Threadedthrough the end of the arm 49 is a sizing screw 50 having a rounded endadapted to bear against the rearward side of the frame 4 on which thewinding mechanism is mounted, see Fig. 2. The sizing screw 50 may beadjusted in the arm 49 of the lever 42 so that its end will contact withthe frame 4 when the cop-supporting frame 6 has been rocked upwardly toa predetermined extent by the increase in diameter of "the winding; Thatis to say, the arrangement is such that when the package has reached apredetermined diameter the frame 6 will have been swung upwardly to suchan extent that the screw 50 will be brought into contact with the frame4 to rock the lever 42 in the direction indicated by the arrow 0 in Fig.2. The rocking of the lever 42 in this manner will cause it to slide thedetent-rod 37 to the left, as viewed in Fig. 2, g

2, the tension-device comprises opposite, piv

oted grids having fingers across which the yarn draws in a sinuous path;it being understood that when the machine is equipped for winding inmultiple a plurality of the, tensions are employed, one foreach strandto be wound into the cop. Only'one of the tension-devices ishereinillustrated, however, and the yarn leads upwardly therefrom to theguiding-slot in the reciprocable thread-guide 10 by which it istraversed on the cop C. Intermediate the tension-device and thethread-guide 10 is a wire breakagelever which is provided with opposite,parallel legs pivoted on a rod 61 extending between a pair of plates 62projecting forwardly from the frame 4, see Fig. 2. 'The yarn 3 drawsacross a horizontal bar 63, which connects the upper ends of the legs ofthe breakage-lever 60, and normally maintains the lever in substantiallyerect position as illustrated inFig. 2. The lever 60 has a right-angledextension 65 at the'lower end of one of its legs which is insertedthrough-a loop 66 at the forward end-of a wire link 67 The opposite end"of the link 67 is hooked into a hole 68 on the elbow-shaped arm 69 of apawl-lever 70. The pawl-lever 70, is pivoted on a pin71projecting'through the sides of a push-bar 72 which is connected at its rearwardend to the sickle-shaped lever 42 for operating-the detent-rod 37previously described. As shown in Fig. 2, the curved portion 18 of thelever 42 is provided on its side withan arcuate slot 7 4: which isengaged by a pin-or roller 75 carried at the rearward end of the ush-bar72. The forward end of the pus bar 72 is supported from a. rockable arm77 having a :pivotal connection with the bar at 78. The arm 77 below thepin 71 to an opposite arm formed with a toe 86. adapted to-be rockedinto position to engage with the rounded teeth 87 on the interior of therim of stopping-wheel 88, see Figs. 5 and 6. The wheel 88 is keyed tothe shaft 89 which drives the traverse-cam 9, see Fig. i 2, and rotatescontinuously therewith during the operation of the machine. The pawl 70and its'arm S5 are rocked from the link 67 through the connection of thelatter with the breakage-lever 60 which is adapted to swing to theright, as i shown in Fig. 6, when released by the breaking of the yarn 3drawing across its horizontal cross-bar 63.. A. finger 90 projectingfrom the arm 69 of the' pawl 70 is adapted to contact with thetop of thepuslrbar 72 to limit the rocking movement of the pawl. Referring to 5,one of the legs of the breakage-lever 60 is formed with a U-shaped bendor crook 92 which is adapted to make contact with the end of a lug 93projecting from'the upper end of the arm 77, which supports the outerend of the push-bar 72. Vhen the push-bar 7 2 has been carried into theposition illustrated. in ig. 5, through the operation of thestopping-mechanism as later explained, the arm 77is rocked to depressits lug 93 to engage it with the crock 92 on the breakage-lever 60. Thisaction causes the breakage-lever 60 to be rocked into vertical positionand held there until the winding operation is started aga1n; it beingobserved that the engagement of the extension 65 on the le of the breakae-lever 60 with the loop 66 on the link 67 permits a slight movement ofthe lever without rocking the pawl 70.

1 The arin 77 also hasa further function in operating the thread-bail 95which lifts the yarn away from the thread-guide 10 upon lifter 95consist-sof a narrow plate extending across the front of the machine inclose association with the traverse-guide 10. The

forward edge of the lifter 95 is rolled over at 96 toadapt it to receivea suitable hinge-rod 97 pivotally mounted in ears98 which projectupwardly from a front cover-plate 100 extending between the sides of theframe 1. Gn the under side of the lifter-plate- 95 is an car 101provided with a hole for receiving the hooked end 102 of a rod 103.Referring to Fig. 5, the lower end of the rod 108 is connected to ahooked extension 104 by means of a turnbuckle 105 which is employed foradjusting the length of the twopart ro'd'. The hook 106 on the extension104 is hooked through a hole in-the end of a finger 107 projecting fromthe side-of the arm- 77. hen the arm 77 is rocked into the positionillustrated in Fig. 5,'during the action of the stopping-mechanism ofthe machine, the connecting-rod 103101 will be pushed upwardly to raisethe forward end of the thread-lifter 95 to lift theyarn y out of theslot in the traverse-guide 10 in the ,of the iniproverd foot-controlwillnow be describedin detail. Referring particularly to Figs. land 5,the arm 40Jof the lever 31,

which is pivoted on the. frame 6, is formed with an abutment on its sideproviding a bearing for a right-angled rod 111 inserted through a hole112 at its end. One arm of the rod 111 projects downwardly from thebearing in the form of a pawl 114 which is provided at its end with asharpened toe 115 adapted to engage with the ratchet teeth 116 of anarcuate rack or quadrant 117. The quadrant 117 has a fixed relationtothe frame 6 and, as herein shown, is constructed as a part of themachine frame 4. The rod 111 for the pawl 114 is held in its bearing inthearm 40 of the lever 31 by means of a cotter-pin 118 inserted througha hole in its end. A spring 120 is hooked through the lower, looped endof the pin 118 and anchored at its opposite end to a web 121 pr0-jecting from the side of a finger 122 on the lever 31. The spring 120acts to rock the pawl 114 to carry its toe 115 toward the teeth 116 onthe quadrant 117 and the upper end of the pin 118 is adapted to contactwith a pin 123 driven into the side of the arm 40 to limit the rockingmovement of the pawl. The engagement of the pin 118 with the stop-pin123 acts to hold the pawl 114 normally just clear of the teeth 116 onthe quadrant 117. It will be obvious from the above description thatwhen the detent rod 37 is released from the lever 31 and said leverrocked under the force of its spring 35, as shown in Fig. 5, the pawl114 will first he carried into engagement with the teeth 116 to thenoperate with a toggle-action to raise the frame 6 to lift the cop offfrom its drive roll in the manner as more fully explained hereinafter.It is also to be noted that the downwardly extending finger 122 on thelever 31 is formed with a lug or abutment 125, shown in dotted lines inFig. 5, which is adapted to strike against a projection 126 on the frame6 to limit the rocking action of the lever 31.

It has been explained that during the winding of the cop the frame 6 isswung upwardly as the package grows in diameter, and to control thismovement of the copcarrying frame it has been found expedient to employa dogging-means as neXt described: Referring to Fig. 4, the doggingmeans consists in an elbow-shaped arm 130 provided with a bearing-rod orshaft 131 pivotally mounted in an arm or extension 13 on the under sideof the cross-strut 17 of the frame 6. The arm or dog 130 is beveled 05on its sides at 135 to provide a wedge-shaped section which engages witha tapered or V -shapec groove 136 out into the side of the quadrant 117.The lever 46, previously referred to, has its hub secured to the bearingrod 131 of the dog 130 by means of a set-screw 137 and it will thus beseen that the spring 45 which connects the lever 46 with the lever 42will act to normally and grooved quadrant, is well known in the art.Referring now to Fig. 4, the controlling-lever 46 for the dog 130 isprovided with a forwardly-extending arm 140 having its end beveled ed toform an inclined face 141 which is adapted to'be engaged by the lowerrounded end of the finger 122 on the lever 31. Through thisarrangementthe finger 122 is caused to rock the lever 46 to release the dog 130from the quadrant 117 when the lever. 31 is depressed at its forwardend, either manually or through the action of the foot-control as laterexplained.

The means for operating the stopping lever 31 and its related mechanismfrom the foot-control is arranged as next described: Referring to Figs.3, 4 and 5, on the crossst-rut 17 of the frame 6 is a bearing 142 inwhich is pivotally mounted a rod 143 formed with a right-angled arm 145at one end. Hooked into a hole at the'outer end of the arm 145 is a link146 which is pivotally connected at its opposite end to the arm 40 ofthe lever 31. On the opposite end of the rod 143 from the arm 145 is'alever- 15() secured fast thereto by a binder-screw 151. The lever 150 isprovided with two holes 152 and 153, either one of which is adapted toreceive the hooked end of a wire rod or link 154. Referring now to Fig.1, the lower end of the link 154 is hooked into the upper'end of a rod155 which reaches down'to a foot lever or treadle 156. In the presenttype of machine shown in Fig. 1 an individual footlever is provided foreach single unit or winding-head on the frame 2 and the levers foropposite units project outwardly from a central horizontal shaft 157 onwhich the series of levers are pivoted. The shaft 157 is held inbearings on the legs or standards 3 which support the frame 2 at itsopposite ends. Each foot-lever or treadle 156 is provided on its sidewith 'a projecting rib or plate 159 formed with a series of holes 160into which the lower end of the rod 155 may be hooked. By adjusting therod 155 in the different holes in the rib 159 the height of the treadlemaybe varied in accordance with requirements of its operation.

Having now described the structure and arrangement of the essentialparts of the machine its method of operation will next be explained;Fig. 2 of the drawings illustrates the parts of the winder in theposition they assume substantially at the start of the windingoperation. The winding mandrel or coptube T is shown as having a slightamount of yarn wound on its exterior, the first layers of the package Cwhose surface is held in contact with the periphery of the driveroll 5under the weight of the pivoted supportingrf-rame; 6. As-illustratedinFig. 1, the yarn y leads up from the supply-bobbin B through the tensiondevice 54, thence across the upper bar 63 of the breakagelever 60, andthrough the eye or notch. in the traverse-guide 10 to the package C. Thepackage or cop; C is rotated through its sur- -face contact with thecontinuously driven drive-roll 5 and the continuously reciprocatingtraverse-guide 1O traverses the yarn g back and forth to depositit inhelical coils which formthe layers of the cop. As the winding increasesin diameter with each added layer of yarn the frame 6 is swung graduallyupward and the dogging-device 130 acts frictionally on the quadrant 117to prevent retrogressive movement of the frame whereby .to eliminatevibration of the package on the drive-rolh It has been explained thatduring the normal operation of the machine the breakagelever 60- ismaintained in erect position by the traveling yarn y leading across itsupper bar 63. lVhen the yarn y breaks or becomes exhausted at its sourceof supply, however, the lever 60 will be released and, acting under theforce of gravity, will tilt forward into the position shown at the rightin Fig. 1. As illustrated more in detail in Fig. 6, this forward rockingmovement of the lever 60 causesits projection 65 to be swung back in thedirectionindicated by the arrow 6. to act through the link 67 to rockthe pawl-lever 70, whereby to raise its toe 86 into position to beengaged by one of the teeth 87 on the stop-wheel 88. The wheel 88 iscontinuously rotated in the direction indicated by the arrow f in Figs.2 and 6, and as the stop-finger 90 on the pawl-lever 7 O is brought downagainst the top of the push-bar 72 the dogging of the pawl on the rim ofthe wheelwill act to slide the push bar rearwardly or in the directionindicated by the arrow 9 in Fig. 6. As before noted, the opposite end ofthe push-bar 72 is connected to the detent-lever 42 by means of itsroller 75 which rides in the arcuate slot 74 in the arm 48 of said leveras the frame 6 swings upwardly. It will therefore be seen that inwhatever position the frame 6 may be the rearward movement of the bar 72will cause the lever 42 to be rocked in the direction indicated by thearrow 0 in- Fig. 2. This movement of the lever 42 acts to slide thedetent-rod 37, which is connected therewith to release its end from thenotch 39 in the arm 40 of the lever 31. Upon the releaseof the lever 31in this manner its spring 35 will cause it to be rocked in the directionindicated by the arrow 7) in Fig. 2 until the abutment on its finger 122brings up against the projection 126 on the under side of the arm 14 ofthe frame 6, see Fig. 5. As the arm 40 of the lever is rocked downwardlyit carries the pawl 114 into enor jumping rantEll7; and operates with atoggle action to .ga-gement with the teeth, 116 on the quad:

liftthe frame 6,.whereby the surface of; the 7 Cop G israi'sed away fromthe peripheryof the driver-0115, as shiowll in Fig. 5,.[ I

The withdrawal of the cop from contact with the drive-roll serves toarrestitsv rotation and meanwhile the yarn y, is raised out from theslot in the thread-guidell) by the thread-lifter 95., This latter actionis effected by the raising of the rod 1034104 under the rocking; motionof the armf77 which is; connected to the push-bar 72, and movedtherefrom in the manner asv later exjplained. Through theabove-describedseqnence of operations, the winding; is arrested and thecop held in raised'position above; the dri-ve roll until the operatorpieces up the yarn.

It. will be observed by reference to Fig.

'5 that-as the arm 40 of the lever 31 is rockeddownwa-rdly the end ofthe detentpivot 30 of the lever 31 causes the rod 37 to be slid fartherback against the pressure of its. spring 45 to. rock the lever '42gtosuch an extent that it will draw the push-bar '72 rearwardly to. removethe pawl-lever 70 from proximitywiththe rim of the stop-wheel 88. Inthis manner thetoe 8.6; on the pawllever 7 O is withdrawn fromengagementwith the teeth 87 on the wheel to prevent chattering orjumping of the pawl as the wheel continues 'to rotate. The. rearwardmovement of the push-bar 72 also serves to rock the arm 77 into theposition illustrated in Fig. 5 tov raise the thread-lifter 95 as beforeexplained and also to depress the lug 93. on the arm into engagementwith the crook .92 on the breakage-lever 60. to return the latter toerect position. i e

In preparing the machine for operation the operator employs both handsfor piecing up the ends and with the present improved arrangement: ofthe controlling means no hand motions arerequired for starting themachine. The loose end on the cop-is drawn off and pieced'to the endfrom the supply bobbin and the free length of yarn, held across the handin order that it may feed properly into the machine without snarling ortangling. As soon as the ends of the yarn are tied or spliced theoperator presses with the foot on. the treadl'e 156 and this actionreturns the 'partsvof the machine to operative position again tocontinuethe winding of the cop. in the manner as next explained:

As the foot-lever I through the rods 1 55 and 154 to rock the leverdownwardly wherebyv the rod 143 is turned to raise its crank arm 145,,as shown in Fig. 4. The arm 145, acts through the link 146 to raise thearm 40 ,of the lever: 31

I to release the pawl 114 from the teeth on the quadrant 117, and thecontinued raising of the arm 40 also serves to release the dog 130 fromthe quadrant. This latter action is effected by the engagement of thelower rounded end of the finger 122 with the beveled face 141 of the arm140 on the lever 46 which rocks the latter againstthe force of thespring 45. Asso'on as the pawl 114 and dog 130 have been released fromthe quadrant 117 in this manner the pressure of the foot on the treadle156 is released slightly and the frame 6 is thus allowed to drop slowlyunder the action of gravity to permitthe cop C to be brought gently intocontact with the periphery of the driveroll 5. i

It will be noted by reference to Fig. 4 of the drawings that as thelever 150 is swung downwardly by the action of the depressing of thetreadle 156 it strikes against the rearward cross-bar 16 of the frame6so that the downward movement of the frame is maintained under thecontrol of the operators foot pressure. It is to be further observedthat the full movement of the lever 150' serves to rock the connectedlever 31 farther than necessary to engage the detentrod 37 with thenotch 39 in the arm 40. That is to say as the arm 40 of the lever 81 isvrocked upwardly its toe 47 comes against the pointed end of thedetent-rod 87 and holds the latter in position to prevent the chatteringor jumping as the wheel rotates.

Furthermore the bar 72 when in this position as illustrated in Fig. 5serves to hold the lever 77 with its lug 93 rocked downwardly inengagement with the crook 92 on the breakage-lever 60, as beforeexplained. The breakage-lever is thus held in erect position until theyarn can be released from the operators hand and allowed to draw acrossits bar 63.- Through this arrangement the breakage-lever 60 is preventedfrom dropping to stop the winding operation as long as the operatorsfoot is held on the treadle so that the starting of the machine isaccomplished without danger of premature stopping before the yarn isreplaced in contact with the breakage-lever. After the operator hasobserved that the machine is operating properly the foot is removed fromthe treadle 156 and the lever 150 is then allowed to rock back toneutral position with the notch 39 in its arm 40 engaged by thedetent-rod 87, as shown in Fig. 2. The parts of the stopping-mechanismwill thus be returned toand maintained in inoperative relation ready tobecome active again upon the breakage of the yarn. i

It will be observed by reference to Fig. 5 that when the winding isarrested the windinginanclrel T is raised above the drive-roll 5 to asufficient extent to give free access to the whole surface of the cop Cso that the operator may readily discover and 'pick up the broken end ofthe yarn. Should it be required to lift the cop still farther this maybe accomplished by pressing on the treadle 156 to draw the lever 150down against the cross-strut 16'of the frame 6, see Fig. 4, when thelever 150 will act to rock the frame 6 upwardly on its pivot 19. It willthusbe seen that with the connecting rod 154 ongaged with the hole 153at the end of the lever 150 the foot-lever or treadle 156 may beemployed to either raise the cop from or lower it into contact with thedrive-roll. In this way the winding machine is rendered completely underthe control of the footlever so that the operators hands are leftentirely free for other duties. In some cases where it may not bedesired to lift the cop from the drive-roll under foot-control the rod154 is hooked into the hole 152 in the lever 150. With this latterarrangement the lever 150 will be operated from the treadle 156 inthesame manner as previously explained to release the pawl 114, andcontinued pressure on the treadle will draw the frame 6 downwardly toeffect a more prompt return of the cop into driving contact with theroll 5.

It will be evident from the foregoing that the present improvementprovides a much more convenient and expeditious method of controllingthe operation of the winding machine than the usual hand-control. Withthe present foot-control both of the operators hands are left free topiece up broken ends so that the winding operation may be started theinstant the splicing is completed without waiting to reach for ahand-lever. Furthermore, the operator is not required-to reach in acrossthe cop to grasp the starting lever and this is a most importantimprovement from a practical standpoint. Usually the operator breaksor'cuts ofi the waste ends of yarn left extending from the knotand holdsthem in the fingers while starting the machine. With the usualarrangement of starting-mechanism it is necessary to reach above the copto grasp the starting lever and ithas been found in practice that thebits of yarn in the operators fingers will often be caught up anddrawninto the package. If not discovered and removedthese loose ends in thecop will be drawn into the twister, doubler or other machine to whichthe package ultimately delivers its supply and the product of suchmachine will show faults from the loose ends corkscrewingor bunchingwith the other strands. .Inother cases the waste yarn will be caught inthe going parts of the machine Where it is liable to cause improperfunctioning of the mechanism and damage to its parts.

' \Vith the present improved arrangement of the controls the operator isnot required to reach or OtllGI'WlSB'GXQI't himself in starting themachine; hence an erect position may be maintained which greatlyreduces'fatigue and lessensthe labor of the operator whereby greaterproductivity is accomplished.

,Furthermore, the product is improvedand the capacity of the machineincreased due to shorter periods ofstopping.

I'Vhile I have herein shown and described a preferred construction of myimproved control-device as applied to a certain type of machine itisobvious that modifications in structure and arrangement and differentmethods of adapting it for usemay be made which would fall within thespirit and scope of the present invention. Therefore, without limitationin this respect, I claim:
